Hi Johannes, My guess is that you missed that get_view[0:8] is a _column-major_ rotation matrix. Transpose it before using it. I decided to take a look at this problem for preparation of better clipping planes in PyMOL. I got it to work in PyMOL using Python, after much fussing about. Here's w

Hi Johannes, Coincidentally, I found myself in need of the same functionality the other day. I came up with this: from pymol import cmd def clipped_by(at,v): x,y,z = at.coord nz = v[2]*(x-v[12])+v[5]*(y-v[13])+v[8]*(z-v[14])-v[11] return nz > v[15] and nz < v[16] def clipped(

Hi, I implemented the coordinate transformation and the selection of atoms outside PyMol, in R. In principle it works, but there seems to be some error, since too many atoms are selected, corresponding roughly, but not completely to an enlarged clipping corridor between the planes defined by

Hey Hongbo, good way of putting it. Indeed, I think thats what seemed most intuetively to me in the beginning, and so I ended up trying to figure out why 'AND' was not giving me the expected selection. Remembering my boolean algebra lecture from back in the days, I suddendly realized that it ha

Hey :) It's good to note that programs are written by programmers, using programmer's logic.The confusion is not so much caused by the simplified expression, but by users with little background in mathematics/logic assessing 'and' and 'or' from a linguistic background. In computer science and math

Hi Martin, You're in the wrong thread! In addition, + is not OR. OR merges expressions, + 'merges' identifiers in an expression. Further, in the code you gave it said 'or'. It seems from this post you wrote 'and' in your script, signifying a mismatch between what you were doing and what you though

I believe the confusion is caused by the simplified selection expression in PyMOL (and some other visualization tools as well). I remember that one of my colleagues once questioned strongly the reason of using OR instead of AND in such situation. The expression: select resn GLU or resn ASP ac
